WlCK-TUBE FOR OIL-STOVES.

SPECIFICATION forming part of Letters Patent No. 480,268, dated August9, 1892. Application filed April 22, 1892- Serial No. 430,195- (Nomodel.)

To all whom it may concern:

Be it known that I, ROBERT Z. LIDDLE, of the city and county of Albany,in the State of New York, have invented new and useful Improvements inWick-Tubes for Oil-Stoves, of which the following is a specification.

The object of my invention is to form wicktubes for oil-stoves in suchmanner that they will contain no chambers for receiving the explosiveand combustible gases generated during the process of combustion or theresiduum of thematerial from which said combustion emanates, thewick-raiser being arranged within the body of the tube and having anopen communication with the oil-chamber of the stove and the portion ofsaid tube which incloses the wick above the Wick-raiser being formed toclosely confine the same, while leaving sufficient freedom for said wickto allow a free upward flow of the oil to feed the flame. This object Iattain by the means illustrated in the accompanying drawings, which areherein referred to and form part of this specification.

In the drawings, Figure 1 is a perspective View of an oil-stove providedwith my improvements. Fig. 2 is an enlarged transverse section of top ofsaid stove and its wick-tube, said section being taken at the irregularline X X on Fig. 1. Fig. 3 is a longitudinal section of said top andwick-tube, taken at the irregular line Y Y on Fig. 2. Fig. 4 is ahorizontal section of said wick-tube at the line Z Z on Fig. 2; and Fig.5 is a plan view, on a reduced scale, of a blank for forming mywick-tube from a single piece of metal.

As represented in the drawings, A designates the oil-reservoir of thestove, and B the top plate of the same, neither of which form a part ofthis invention, but both of which will be found fully described and setforth in my application, Serial No. 384,263, for a patent, filed in thePatent Office March 9, 1891.

O designates my improved wick-tube,which includes a front 1, back 2, andends 3, which may be formed of two pieces, as shown in Figs. 3 and 4,interlocked at opposite ends, or it may be formed of a single piece madein the form shown in Fig. 5 and interlocked at one end.

The ends of said wick-tube have an approXimate trapezoidal form, whoselower portion is formed of parallel vertical lines and its upper portionformed by a vertical line, which preferably is a continuation of thevertical line at the front part of the lower portion of said end, and aninclined line, which joins to the opposite Vertical line at the lowerportion of said end, whereby an obtuse angle is formed at the rearmostside of the end of said tube. A passage 5, whose inclosing walls will bepractically parallel, is formed to contain the wick alone, and a passage6, having an increased capacity to contain both the wick-and wick-raiserD, is formed in said tube to have a free communication with theoil-reservoir A, both of said passages being formed in the body of saidwick-tube by means of the depression 4. When formed of two pieces, asshown in Fig. at, the ends 3 are preferably formed on the back 2, andthe front 1 is provided with overlapping parts, the two parts beingsecured together by solder or other suitable means. The tube 0 may besecured to the top plate B by soldering or other suitable means wherebya gas-tight joint can be made. When the wick-tube C is made of a singlepiece of sheetmetal similar to the blank shown in Fig. 5, the indentedportion 4, j ournal-holes 8 for the pivots of the wick-raiser D, and anotch 9 should be made therein before said blank is bent to form saidwick-tube. Preferably slightly-indented lines 10, 11, 12, and 13 aremade in said blank at the points where the bends are to be made to formsaid wick-tube, the bend at the line 13 being made to form a slightoverlap to engage over the edge of the front 1.

The wick-raiser D, which is of an old and well-known form, is j ournaledin the ends 3 of the wick-tube, and its shaft 14: is provided with ahead 15, whereby said wick-raiser can be rotated when occasion requires.It will readily be seen that by this construction,while I have providedample space for an upflow of oil through the wick while it is in thepassage 5, there is no vacant space wherein gases can accumulate andthat a free opening is formed at the lower end of the wick-tube from thelower side of the wick-raiser D into the oilreservoir A to form anunobstructed passage from said wick-raiser into said oil-reservoir,

whereby any incrustation or other debris which may be formed on the wickor deposited on the wick-raiser during the manipulations of the latterwill be discharged therefrom and deposited in said oil-reservoir.

WVhat I claim as my invention, and desire to secure by Letters Patent,is-

l. A Wick-tube having one of its principal sides formed by a verticalplane, the opposite side having at its lower part a short vertical planefollowed by a depressed portion which forms a contracted passage forcontaining a wick, the lower part of said depression containing awick-raiser and the extremities of the last-named side being bent at anobtuse angle to said vertical plane, and ends having an approximatedtrapezoidal form corresponding to the extremities of said sides, asherein specified.

2. A wick-tube comprising a large open passage below the wick-raiser anda contracted passage above said wick-raiser, one side of bothof saidpassagesbeing formed on the same vertical plane and the other side ofboth of said passages being parallel to said plane, but at differentdistances therefrom, the upper passage being adapted to easily inclosethe Wick and the lower passage forming an open communication from thelower side of the wick-raiserinto the oil-reservoir, the ends of saidtube having an approximated trapezoidal form and the back of said tubebeing impressed to form the contracted upper passage for the wick, asand for the purpose specilied.

3. A wick-tube having a large open passage of uniform size from thelower side of the wickraiser to the lower end of said tube and acontracted passage of uniform size from the upper side of thewick-raiser to the upper end of said tube, one side of both of saidpassages being formed on the same vertical plane, as and for the purposespecified.

4. A wick-tube composed of one or more pieces and having an upperpassage of uniform size adapted to inclose the wick and a lower passageof uniform size,but of greater area than said upper passage, one side ofboth of said passages being formed on the same vertical plane, incombination with a revoluble wick-raiser arranged at the junction ofsaid passages and fitted to discharge the debris from the wick into theoil-reservoir, as and for the purpose herein specified.
